Minimum heat flow from the core and thermal evolution of the Earth

The role of heat flow coming from the core is often overlooked or underestimated in simple models of Earth's thermal evolution. Throughout most of Earth's history, the mantle must have been

Thermal and compositional stratification of the inner core

The Sensitivity of Core Heat Flux to the Modeling of Plate‐Like Surface Motion

The generation of a magnetic field and the presence of tectonic plates are fundamental aspects of Earth's evolution. Viable dynamic models of terrestrial mantle convection therefore require the

On Destruction of a Thermally Stable Layer by Compositional Convection in the Earth's Outer Core

We discuss destruction of a thermally stable layer in the upper part of the Earth's outer core by compositional convection excited at the inner core boundary. We propose to use the radial

The Iron Invariance: Implications for Thermal Convection in Earth's Core

Convection of the liquid iron (Fe) outer core and electrical properties of Fe are responsible for the geodynamo that generates the geomagnetic field. Recent results showed the thermal conductivity of

Thermal histories of the core and mantle

The influence of potassium on core and geodynamo evolution

We model the thermal evolution of the core and mantle using a parametrized convection scheme, and calculate the entropy available to drive the geodynamo as a function of time. The cooling of the core

Influence of initial CMB temperature and other parameters on the thermal evolution of Earth's core resulting from thermochemical spherical mantle convection

Here we present a wide‐ranging parameter study of the effects of initial core‐mantle boundary (CMB) temperature, concentration of radioactive potassium in the core, and density difference between
